Second World War posters

The first planning for Air Raid Precautions took place in 1924 and was based
on the experience of German air raids on Britain during the First World War
in which over 1,400 had been killed. But it was only after Hitler started to
pursue an aggressive foreign policy in the 1930s that plans to protect the
civil population in the event of a new war began to take shape. In January
1939, a pamphlet entitled “National Service”, with an introduction from
Prime Minister Neville Chamberlain, was delivered to every British household
detailing the various organisations that one might join.
